Rafael Nadal drops unexpected praise on Roger Federer

Who has the best forehand on the ATP Tour? Juan Martin del Potro answered this question a few days ago at the Madrid Open, now it was Rafael Nadal's turn. The King of Clay was unsure about making a definite choice, but he gave a good insight on the topic.

'It's difficult,' he admitted. 'At the end, I don't think all of the forehands are as good. I think that maybe my forehand is better than (Roger) Federer's on clay, and hard court or grass I think that his forehand is better than mine of course.
